So, the models have backed off on a significant snowstorm for areas such as Central PA for Thanksgiving; yet, if you are traveling north of Central PA line there will be some snow but not a bonanza mostly in NY State. Not enough cold air draining into those areas.
Yet, east of that line we will get a nice dousing of rain which should end fairly early in the afternoon on Thanksgiving. So, it won't be a total washout. After this VERY cold air will blow the door open into the region starting Friday.
